Task Type ========= xCAT supports following types of task which could be set in the chain: * runcmd :: runcmd=<cmd> Currently only the ``bmcsetup`` command is officially supplied by xCAT to run to configure the bmc of the compute node. You can find the ``bmcsetup`` in /opt/xcat/share/xcat/netboot/genesis/<arch>/fs/bin/. You also could create your command in this directory and adding it to be run by ``runcmd=<you cmd>``. :: runcmd=bmcsetup **Note**: the command ``mknb <arch>`` is needed before reboot the node. * runimage :: runimage=<URL> **URL** is a string which can be run by ``wget`` to download the image from the URL. The example could be: :: runimage=http://<IP of xCAT Management Node>/<dir>/image.tgz The ``image.tgz`` **must** have the following properties: * Created using the ``tar zcvf`` command * The tarball must include a ``runme.sh`` script to initiate the execution of the runimage To create your own image, please reference :ref:`creating image for runimage <create_image_for_runimage>`. **Tip**: You could try to run ``wget http://<IP of xCAT Management Node>/<dir>/image.tgz`` manually to make sure the path has been set correctly. * osimage :: osimage=<image name> This task is used to specify the image that should be deployed onto the compute node. * shell Causes the genesis kernel to create a shell for the administrator to log in and execute commands. * standby Causes the genesis kernel to go into standby and wait for tasks from the chain. ...
